I see your point here.....As much as I love my Galaxy Note 2 for all it can do..and does....For me to stream music from or to my PC, I had to configure DLNA server settings...most PC users don't even know what these are
...so it is a pain for most. and DLNA, while powerful and much higher defination/audiophile than bluetooth audio( which is very lo-fi at best with low data rate/poor bandwidth for good audio)...DLNA requires a couple of hours for most Android or PC users to get it working...that's alot of committment...you have to want it badly
On the other hand, say I just shot a new goliath Grouper video like this one
The same 20 meg per second data rate and 2 gig mp4 video that I would have on my PC after rendering it for PC or Youtube Uploading, will play just like this on my android!!!!!
It plays just like a real computer.....My ipad, and Iphones ( as far as I know), require SPECIAL ENCODES RENDERED FOR THEM---for weaker cpu and lesser video player software in the IOS system....so, you have to waste time, often when you don't have it, making a special low res version of the video for the Apple phone or Ipad...I prefer the drag and drop, and be done
